Merlin-based start-to-end simulations of luminosity stability for the ILC

In this paper, we report the progress and status of a full-featured so-called start-to-end simulation based on the MERLIN library. The current model comprises acceleration in the superconducting main linac, beam delivery system and finally collision at the IP. Realistic modelling of the beam-beam interaction is included by using the code GUINEAPIG. Results on ground motion modelling and trajectory control are presented.
